He can once again order a rearrangement of American forces inside the country, as he did in August, when American commanders declared that newly trained Iraqi forces would “clear and hold” neighborhoods with backup support from redeployed American forces. That strategy collapsed within a month, frequently forcing the Americans to take the lead, making them prime targets.

There is no assurance, though, that another redeployment of those forces will reduce the casualty rate, which has been unusually high in recent weeks, senior military and administration officials say. The toll comes just before midterm elections, in which even many of his own party have given up arguing that progress is being made or that the killing will soon slow.

Or Mr. Bush can reassess the strategy itself, perhaps listening to those advisers — including some members of the bipartisan Iraq Study Group, the advisory commission charged with coming up with new strategies for Iraq — who say that he needs to redefine the “victory” that he again on Thursday declared was his goal."
